Embodiment Construction
[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0049] During the execution of some processes in the computer, the system time of the computer is required to participate; and in the process of adjusting the coordinated universal time for leap seconds, the coordinated universal time may be moved forward by 1 second (negative leap second, that is, one minute consists of one second). 59 seconds), or, dial back 1 second (positive leap seconds, i.e. a minute consists of 61 seconds), whic...

The invention provides an information processing method and device and a server. In the prior art, when leap second adjustment is carried out for the coordinated universal time, the coordinated universal time can be dialed forwards for one second (negative leap second, i.e., one minute is composed of 59 seconds), or the coordinated universal time can be dialed backwards for one second(positive leap second, one minute is composed of 61 seconds); if in the system time of a computer, one minute is composed of 59 seconds or 61 seconds, processes which the system time needs to participate in can break down. According to the invention, before leap second adjustment, the system time of the computer is controlled to stop and to be synchronized with the coordinated universal time, thus, during the leap second adjustment process, the system time of each computer is already not synchronized with the coordinated universal time, i.e., in the system time of each computer, the phenomenon that one minute is composed of 59 seconds or 61 seconds does not exist, thus, processes, in each computer, which the system time needs to participate in do not break down.
Description
technical field [0001] The present invention relates to the field of communication technologies, and more particularly to an information processing method, device and server. Background technique [0002] For computers, time is very important, especially the requirements for time synchronization of various computers in the network are very high. NTP (Network Time Protocol, Network Time Protocol) is a protocol used to synchronize the time of various computers in the network. Its purpose is to synchronize the system time of the computer to UTC (Coordinated Universal Time, Coordinated Universal Time), so that the system time of each computer in the network is synchronized. [0003] However, due to the non-uniformity and long-term slowness of the earth's rotation, there will be a time error between atomic time and UTC. When the time error is greater than 0.9 seconds, the International Bureau of Weights and Measures will periodically check the UTC at the end of the year, mid-year...
